10 stropping means with a member that will cooperate with the other frame for retainin the blade in shaving relation to the guar which member is adapted to cooperate with a strop for tensioning the latter in connec- 15 tion with the stropping means when the blade is to be stro ped.

Another o ject of my invention is to pro-v vide an improved' holder adapted to retain a blade in position to cooperate with the uard and with the strop for stropping the e ge of the blade.

My invention comprises a frame provided with a handle and having a guard, a second frame pivotally connected with the first named frame and provided with ablade holder and with a movable member having a portion adapted when the member is in one position to cooperate with the first named frame to cause the blade to be retained in shaving relation to the guard, and when the member is in a diiierent position the frames will be released and the `member will cooperate with a strop during reciprocations of the razonalong the strop for stropping the blade edge. A featureof the construction is such that when the direction of reciprocation of the razor along the strop is -reversed the pivoted frame that carries the blade will tilt respecting the strop to initially lift the blade edge from the strop to prevent said ,My invention comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part hereof, wherein Fig. 1 is a plan view of a safety razor embodying my invention;

Fig. 3 is a view similar to Fig. 2 showing the blade released from the guard and the parts in position for stropping;

Fi s. 4 and 5 are sectional views illustrating itferent positions of the razor respectin a strop; v

ig. 6 1s a section substantially on line 6, 6, 1n Fig. 2, part being broken awa Fig. 7 is a face view illustrating the blade holder and blade from the side opposite that shown in Fig. 1;

Fi 8 is a cross section on line 8, 8, in Fig. g?, and

Fig.-9 is a sectional detail of a modification. Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a suitable frame shownl provided with a blade guard 2, indicated in comb-like form, and with a handle 3 which may be attached to the base 1a of frame 1 in any desired way, as by screw threads at 4. A second frame is indicated at 5 and is shown comprising a base 5a and spaced uprights 5b between which a blade holder is pivotally su ported. The frame 5 is pivotall supported) u on the frame 1 so that one frame will'roc relativel to the other. for which purpose the base o frame 1 l' is shown provided at its endswith upwardly Y ting edge in shaving relation to guard 2.`

Near opposite ends of the guard stops 2a'are located for retaining the blade u on the guard. In the example illustrated t e stops 2a are adapted to engage the corner portions 7 of the blade holder to retain the blade upon the guard when frame 5 is tilted toward the guard, (Fig. 2). The blade edge may engage the stops 2a if preferred. A member 9 1s outwardly disposed lugs 5 pivotally supported upon the lower portion of frame 5 by means of pivots 10 entering the uprights 5b, and said member is provided with a lateral projection 9a that is adapted to engage the base 1a for retaining the blade in shaving relation to the guard. The member 9 is sliown provided with a linger piece 9 for convenience in manipulating it. In the example illustrated when frame 5 is tilted, as in Fig. 2, the parts 7 of the blade holder will engage the stops 2a of the guard and the member 9 will be folded inwardly respecting frame 5 so that the projection 9a will bear upon the base and thereby retain the arts in shaving position. When the mem r 9 is swung outwardly from frame 5 the projection 9a will be released from base 1a and will engage the base 5a of frame 5 to retain the member in an outwardly eX- tending position to be engaged by a strop 11 when the blade edge is to be stropped, and the frames may rock or rotate relatively one to another, (Figs. 3, 4 and 5). lVhen the member 9 is in the last named position it will extend outwardly respecting frame 5 in position to engage strop 11, and from the opposite side of frame 5 projects a strop tensioning arm 5c. A strop engaging roller or shaft 12 is journaled in frame 5 and provided with a gear 13 in mesh with a gear 14 secured to the blade holder. 1 The roller or shaft 12 is shown comprising a tube 12 located between the uprights 5b and av shaft member 12a extending within said tube and journaled in the uprights 5b. the gear 13 being secured to or formed on shaft member 12a and located on the outside of the adjacent upright 5b. The parts 12 and 12a are secured together' for rotation by means of dents 12 in the tube entering depressions in the shaft members, (Fig. 6). The strop-engaging shaft or roller 12 is located in the space between the member 9 and the projection 5c.

Vhen the blade is to be stropped the strop 11 is passed through the space between the uprights'b under the shaft or roller 12 and upon the member 9 and the strop tensioning arm or projection 5c in manner illustrated in Figs.`4 and 5. lVhen the strop is held taut the razor will be reciprocated along the strop and the tension of the strop against the shaft or roller 12, caused by the member 9 and arm or projection 5c, will rotate said shaft or roller, whereby through the gears 13, 14 the blade holder and the blade will be rocked to drag upon the strop behind the razorin a well known way for stropping the blade edge. Wien the blade has been stropped the razor is removed from the strop and the parts will be adjusted for shaving, as indicated in Fig. 2. At the initiation of a reverse stroke of the razor along the strop the frame 5 will turn on its pivots to cause the blade edge to ise from the strop to prevent cutting the atter.

The blade holder illustrated comprises a plate-like member 7a against which the blade 8 may be placed with its cutting edge projecting beyond said member. The member 7a is shown provided with laterally disposed lugs 15 having polygonal holes 16 adapted to receive pivot 17 at one end that is journaled in a bearing hole in the adjacent upright 5b and a pivot 18 at the opposite end to which the gear 14 is secured, said pivot being journaled in the adjacent upright 5b. Said pivots have polygonal portions 19 receiving the corresponding holes 16, andthe inner ends of said pivots are riveted over at 20 to retain the parts for. rotation together. The member 7 a is shown provided with spaced projections 21 adapted to enter association complemental apertures 8a in blade 8 for retaining the blade in shaving position on member 7a so that the blade will not shift thereon. I have illustrated the apertures 8a in the nature of a designation, shown in the form of letters which may be of any suitable character. The blade holder member 7a is provided at its rear portion adjacent to the rear or heel of the blade with retaining members 22 having jaw portion 22a adapted to receive or grip the adjacent heel portion of the blade with the blade in shaving position on said member. The jaw-like members 22 are pivoted upon member 7a at 23 so as to swing away from said member to release the blade and toward said member to grip the blade. The members 22 may be formed by stamping them out of suitable sheet metal and folding their outer portions to form the jaws 22a, the bent portions 22 of said members opposing the heel of the blade. In the form shown in Figs. 1 to 7 the rear portion of blade holder member 7a is offset at 7, (Figs. 4 and 5), to receive the relatively fiat shank-like portions 225 of the members 22 so that they may swing between the blade holder plate 7a and the blade. At opposite ends of the blade holder plate 7a are located lugs 24 which extend outwardly from the )late and reversely over the plate in spaced re ation thereto so that when the members 22 are closed against the blade their outer edge portions 22a will squeeze under and against the overlying portion of the adjacent lug 24 which will grip the members to retain them in set position. The adjacent corner portions of blade 8 are provided with recesses or notches 8b of such dimensions as to pass over the lugs 24 when the blade is beingr placed upon the blade holder or removed therefrom to engage the apertures 8a of the blade with the projections 21 of the blade holder. j

In the modification shown in Fig. 9 the blade holder plate 7a is flat and without the offset portion 7 and the members 22 are pivotally supported on the exterior thereof to blade holder,

receive the tween.

Instead of using two jaw members 22 it will be understood that one of such jaw members ma be used for cooperation with theblade an pivoted in any desired location at the rear of the blade holder plate 7a. The projections 21 of the blade holder when located within the apertures 8a of the blade keep the latter from sliding rearwardly 'along the because of the proper co-relation between said projections and apertures, and the jaw members 22 retain the blade in proper position upon the blade holder plate s0 that the blade will be retained in proper relation to the guard for shaving. If a blade not having proper associate or complemental openings tocooperate with the projections 21 of the blade holder were to be laced upon the latter such bladewould not be properly retained since pressure against the blade edge, such as in` shaving, would tend to slide the blade rearwardly 4against the jaw members 22 and displace them to some extent so that the blade edge would notbe retained in proper shaving relation to the guard. Fur thermore, if it were attempted to place upon the blade holder plate a blade not having recesses or notches, such as 8b, to receive the lugs 24 such blade could not be placed in proper position upon the blade holder, as said lugs would o pose the blade and prevent it from being tted in shaving position upon the blade holder.

Changes may be made in the details of construction and arrangement of parts set forth, within the scope of theV appended claims, without departing from the spirit of my invention.
